Patented July 13, 1948 UNITED STATES-Q PATENT, OFFICE FOUNTAIN PEN CAPHAVING A MULTIPLE CYLINDER, SINGLE AXIS CALENDAR Sophie Gonczi, UnionCity, N. J. Application July 29, 1944, Serial No. 547,140

f 1 Claim. 1 This invention relates to new and useful improvements in a,writing instrument and more particularly to a cap for a fountain penhaving a multiple cylinder,-single axis calendar. More specifically, thepresent invention proposes the construction of a writing instrumenthaving a built-in calendar capable of recording the day, month and yearfor many years.

A further object is to provide aninstrument as aforesaid in which theday, month and year fountain pen cap. I

Fig. 3 is an enlarged perspective view of a lock ring of the cap.

Fig.4 is an enlarged perspective view of the I barrel of the cap.

Fig. 5 is an enlarged perspective view of the year cylinder of the cap.a

Fig. 6 is an'enlarged perspective view of the month cylinder'of the cap.

Fig. .7 is an enlarged perspective view'of the outermost day cylinder'ofthe cap.

Fig. 8 is an enlarged perspective view of the intermediate day cylinderof the cap.

Fig. 9 is an enlarged. perspective view of the innermost day cylinder ofthe'cap.

The present invention is adapted for use with various types of writinginstruments such as penc-ils andrpens. l For simplicity,.it is shownapplied to the cap of a fountain pen but it will be 'understood that itcan also be applied to the body 'of apencil' or pen.

The fountain pen, according to this invention,

comprises 'a pen part ID on which is secured a cap which functions likea'conventional fountain pen cap to coverthe pen-point when the penis notin use and is pushed on the end remote iromthe pen point when the'pen isin use.

Cap ll comprises a barrel |2 including a lower cylindrical portion-|3having a window l4 for viewing thev days of the week as will presentlyappear.

threaded wall spaced from the portion I3 and numbers of cylinder 24 maybe viewed. The outthis. open, and neck 22 extends therethrough.

has an intermediate cylindrical portion I5, of larger diameter than theportion l3, provided with a window It for viewing the months as willpresently appear. larger upper cylindrical portion II in which is formeda window I8 for viewing the years as will presently appear, the numberl9 being printed on the portion IT at one side of the window. The top ofthe barrel has external threads l9 and at the bottom of the barrel is aninternal connected thereto.

In the barrel are disposed five thin cylinders fitting one within theother, each of the cylinders being rotatable and slidable relative tothe other cylinders. The innermost cylinder 2| has a contfnuousuninterrupted cylindrical wall which at its upper portion has a neck 22closed at its top .by a wall 23. On this cylinder 2| are longitudinalrows of numbers representing days of the week. Each row has seven daynumbers, as is clearly shown in Fig. 9, each successive row startingwith one day later than the row before.

The next cylinder 24 is similar to the cylinder 2| except that it islarger so that cylinder 2| fits inside of it with a sliding fit, and itis provided with a longitudinal window 25 through which the numbers ofcylinder 2| may be viewed when the cylinders are properly adjusted forThe top of the neck 26 of cylinder. 24 is The next cylinder 21 issimilar to cylinder 24 but is larger so that cylinder 24 can fit withinit,

with its neck extending through the open end of the neck 28 of cylinder21.

Cylinder 21 is provided with awindow 29 through which the side diameterof cylinder 21 is slightly less than the inside diameter of portion H]of barrel I2 so that it can rotate therein.

A cylinder 30 is mounted on cylinder 21, neck 28 extending through theopen neck 3| of cylinder 30. The names of themonths are printed oncylinder 30, this cylinder being disposed with its lower portion in thebarrel portion l5.

A cylinder 32 is mounted on cylinder-30, neck 3| extending through theopen' neck 33 of cylin- The lock ring. 34 is loosened and neck 33 1s Thebarrel |2 also has a still seized in a persons fingers and cylinder 32is rotated thereby until the current year numbers show through windowI8. The neck 3| is then seized and cylinder 30 rotated until the currentmonth shows through the window I8, neck 33 being held stationary by thefingers of the other hand during rotation of the cylinder 30. The neck28 is then seized and cylinder 21 rotated until the current row of daynumbers shows through thewindow i4. Necks 3| and 33 are held stationaryduring rotation of cylinder 21.

If the current row of day numbers is not on cylinder 21, the window 29is lined up with window l4 and neck 26 is seized and cylinder 24rotated. If the current row of day numbers is not on cylinder 24, thewindow is lined up with windows 28 and I4 and neck is seized andcylinder 2| rotated until the current row of day numbers is visible. 3

The lock ring 34 is then rotated to screw it firmly on the barrel, thelock ring pressing downward on the portion of the cylinders surroundingtheir necks, thereby holding all of the cylinders in their properadjusted position.

Each of the necks is serrated at its top to provide a finger hold. Itwill be noted by reference to Fig. 1 that the protruding necks make avery attractive top ornament for the fountain pen cap. It iscontemplated that each of the cylinders willbe made of thin metal suchas hard brass which slides easily and is strong. The construction of thecylinders having two cylindrical portions connected by an annularportion provides a very strong structure able to withstand muchrotating.- While three day number cylinders have been shown, providingample space for the numbers of rows of numbers needed to show the daysof the month a week at a time, more or a less day number cylinders maybe employed if desired.

The internally threaded wall 20 provides means for retaining the bottomof the day number cylinders and also for screwing on the part Hi. It isa feature of the present invention that the innermost day numbercylinder provide the inside wall of the cap. The names and numbers maybe printed on the cylinders in any desired manner, but they arepreferably first etched A fountain pen cap comprising a cylindricalbarrel having at its bottom, an inner short wall interiorly threaded, alower cylindrical portion spaced from said short wall, a bottom wallconnecting said walls, the upper .portion of saidbarrel being steppedtwice providing an upper cylindrical portion and an intermediatecylindrical portion, the upper cylindrical portion of said barrel beingexteriorly threaded, said upper cylindrical portion having a smallwindow, said intermediate cylindrical portion having a small window, alongitudinal window in said lower cylindrical portion, the latter havingthe days of the week indicla thereon along one side of said longitudinalwindow and the first two numbers of the year indicla along one side ofthe window in said upper cylindrical portion, three interflttingcylinders disposed in said cylindrical barrel with their lower endsdisposed on said bottom wall,

each of said cylinders having a neck'at its upper end, the innermostcylinder neck extending through and beyond the intermediate cylinderneck and, the intermediate cylinder neck extending through and beyondthe outer cylinder neck, said outer cylinder neck extending above saidbarrel, said intermediate and outer cylinders each having a longitudinalwindow and said three cylinders having indicia of the days of the month,

two additional cylinders, one of said cylinders being disposed withinsaid intermediate cylindrical portion and having a neck surrounding andshorter than said outer cylinder neck, months of the year indicla on thesaid one cylinder, the other of said cylinders being disposed withinsaid upper cylindrical portion and having a neck surrounding and shorterthan the neck of the first of said additional cylinders, the second twonumbers of aseries of years indicla on said other cylinder, and aretaining ring surrounding said other cylinder neck and uppercylindrical portion and screwed on the exterior threads of said uppercylindrical portion for retaining all of the aforesaid parts of said captogether.
